I have tried so many ways to fix this problem. I've posted on two forums already and I haven't gotten any internet access at all.

( http://www.bleepingcomputer.com/forums/t/218644/wirless-works-direct-connection-doesnt-for-one-computer-only/ )

I have been trying to fix this problem since the day it unexpectedly stopped working (April 9th). I have tried most of the possible solutions that were provided by one of the tech support guys, but not good. The only possible reason this could have happened is that a virus may have something to do with it. Please help! :thumbsup:

I won't post a Hijackthis or anything until I'm told to do so. Thank you again.

**Note - you don't have to read the entire thread, it's just the first post that really matters. If you're curious, I tried the current possible solutions and none of them worked. Which is why I'm assuming that a virus may be preventing me from accessing the internet or it did something to it for the 2 hours I was away from the computer.

My operating system is a Windows Vista and it says that it is designed for Win 95, 98, ME, XP, or 2000. Wouldn't that cause some problems if it doesn't even mentione Vista?

They told me it is OK to use with Vista
The references to 98/XP only were for other programs listed at the bottom of the page

Ok, tried it out, but here's the thing...

When I right-click LSPFix and Run as Administrator it mentions that No Problems were found. I'm using the admin and only account on that computer.. I pressed finish and I still wasn't able to access the internet. It told me that no changes were necessary... So I tried restarting the computer to see if that helped and no luck. :thumbsup:

Now, if I just double click it without running as administrator, I get this..

It says Winsock 2 Registry Key could not be accessed or it's missing... If it's because I'm not running as administrator then that may be the reason it can't access it... But even if I do, it still hasn't fixed the internet issue. If in reality I am indeed missing the Winsock 2 Registry Key, then could you provide a link to it?

If you are indeed missing a windsock key SFC.exe should fix it

Other than that I am out of suggestions
Either a reformat/reinstall or possibly submit a HJT log:

Do you think if I restore to the day before the problem started using the SYSTEM RESTORE, would be able to solve the problem?

I only have two restore points left before the day the problem occurred! So please answer as soon as possible before those restore points disappear.

Thank you.

>>EDIT<<
Sorry, for editting so much.. But I want to get as much questions answered... And reformatting my system is something I really don't want to go through with. Anyway, do you think if I buy a USB (wirless) adapter for my desktop would I be able to connect to the internet? Or this computer wouldn't be able to find a connection at all?

And well, I scanned the computer with sfc.exe and it didn't ask me for any installation CDs and said this: "Windows Resource Protection did not find any integrity violations". So that means I already have winsock. :thumbsup:

If nothing else works, I'll try a Hijackthis Log.

>>2ND EDIT<<
Well the system restore did no good... :flowers:

If this is a tower and not a laptop, do the LED's light up when the LAN cable is plugged in?
Qther than that, my last post still stands
Sorry

Yes, it is a tower computer and if you mean when I plug in the ethernet (LAN) cable in the back of the computer then, yes, it does light up (yellow/orangey).

But.. If I buy a USB wireless adapter, do you still think I won't be able to connect to the internet??? :thumbsup:

>>EDIT<<

Well, I just need one more answer from you. After that answer and if you don't have any more suggestions, then please close this thread. I'm gonna try posting on the HijackThis boards. Thanks for your help. If you do indeed think I may be able to access the internet with a USB wireless adapter then that'll be better than nothing. If not.. Then I really don't know what else to do, reformatting will really be a pain considering I have so many important files on that computer that surpass a disc/flash drive limit (capacity)...

I believe I have found my solution!

Here's what I did. I went to my Device manager. To Network Adapters and clicked on properties... Then I changed my Speed and duplex settings to 10 Mbps Half Duplex. And problem solved!!!

I'll probably try to check the speeds a bit, but 10 Mbps Half Duplex seems to have solved my internet problem at least.

Thanks a lot for your help, I really appreciate it. And you can now close this thread. :thumbsup:

It was a like a dream too... Apparently after an update that happened last night, I was ready to go to school and just shut down my computer. I come home from school today and find that I'm back at Limited Connectivity... :thumbsup: I just have the worst luck...

My IPv4 and IPv6 are both at the Limited, status..

I'm wondering... Could my driver be outdated? And could that be the cause of my problem? My Driver Date says 5/3/2007.

>>EDIT<<
I got it to work again... I really don't know how.. I just waited a few minutes my status was Local Only. I switched it back to 10 mbps for the Speed and my internet returned... I have no idea what's going on with my computer. I tried updating the driver (while online) and it said that I already had the latest version.

For some reason, I don't think this is going to be a permanent connection and I'm probably going to lose it again tomorrow and go through the same crap over again... I hope a solution is found soon.

Thanks again for the help.
